Hi first time poster and looking for help my wifes 2014 Qashqai is getting annoying and my wife is getting grumpy with me :D ;)
it started some time ago when the front sensors stopped working and had a flashing sensor light. so turned them off and all good then the rear ones stopped
i have so far checked both buzzers and they are fine and replaced them checked the earth's disconnected the battery etc tried a new sensors etc

running Carista i get the following faults
b2722 .29 etc relating to both front and read sensors i doubt that could all be faulty
B20bd battery current sensor
b20be battery temp

so i don't know what to try now thinking battery fault ?

any ideas or help would be great thank you

I don't know what Carista is but those 3 DTCs are valid Nissan error codes. The battery seems to have some problems...or its sensors do?

The .29 is not included in diagnostics...the DTC is just B2722 (REAR RIGHT SIDE INTERNAL SENSOR)
• Sensor is not configured.
• Sensor is open or short circuited.
• Sensor element malfunction.

Will Carista clear those DTCs?
